So now that I have my car back I see the 4 cats and the placement of the Resi. May I ask where Rob puts the High flow cats in the exhaust system, I assume he puts them in the same area as the rears? On that setup do they still keep the Resi in the same place? I see that its a 2 in and 1 out design with a single pipe going into the muffler at the rear, is that correct? I would think that would be a bottle next on the exhaust. I have a set of High Flow Cats so I need to know where the best placement for them. I will try going with the catless setup since this is a track only use car. Does anyone mess with installing a X pipe in the system ? Thanks
